'lhe present invention relates to tooth brushes; and its object, brieflystated, is the io provision ot an article ot thecharaeter in dicatedembodying a bristle-carrying member or brush proper which may be readilydetached when the bristles become worn and replaced by a new one., theinvention residia ing primarily in the improved means or devicesemployed to retain the bristlecarrying member in place.

Referring more particularly to the accompanying drawing,"

Figure l is a part-sectional side elevation of one term which theinvention may take in practice.

Fig. 2 is a trent view thereof, also partly in section, but with thebrush proper omitted at and the head and the adjacent part or member otthe handle separated from the other part or member oit the handle.

As represented in said drawing, the im proved brush embodies a handle land a ao head or holder; the latter being indicated generally at l andbeing provided with a recess ll to contormably and removably receivetherein the bach ot the bristle-car rying member or brush proper.

'lhe yhandle l is structurally .separate trom and capable ot rotationwith relation to the shank d ot the head. 'lhe inner end ot the handlehas attached to it a threaded stem 2, forming a locking element andterminating in a point 3; said stem adapted to be screwed into althreaded axial passage l2 in the shank 4f which opens through the wallof the brush-holding recess ll. rl`he brush back 5 has formed in itscircumferential wall, at one end of its niedian line, a hole or seat 7to receive a lateral spur 8 on the wall of recess ll; and at the otherend of its said median line it is formed with a hole or seat 6registering with the open end ot the threaded passage l2.

l claim as my invention:
